Ap ncation filed June 2-1,

This invention relatesto window screens and has forits object to provide, in a manner as hereinafter set forth, aside extension for connection to the screen for the purpose ofadapting the screen for use in connection with window frames of different sizes and with the extension constructed and arranged 'to permitl of the screen, with the extension attached thereto, to be conveniently mounted in and removed from thewiirdow frame.

Afurther object of the invention is to proride, in a manner as hereinafter set forth, a side extensionforwindow screens capable of being conveniently adjusted relatively to thescreen and when adjusted detachably secured in such position.

A further object of the invention is to provide, in a manner as hereinafter set forth, a side extension for window screens whereby it will enable the screen to be mannfactured to i standard sizes and then by employing; theside extension the screen can be fitted to larger. or odd sized window frames.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a side extension for window frame which is simple in its construction and ar-' rangement, strong,- durable, compact, thoroughly efficient in its use, readily installed with respectv to the screen, expeditiously adjusted, and comparatively inexpensive to manufacture. I

Vitlfthej foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shownan' embodi-' ment of the invention, but it is to be understoodvthat changes, variations and modifications canbe resorted to which fall within the scope of the claims hereunto appended.

body.- The end bars of the frame 1 are indicated at 3, 4. The foregoing elements are of known COIlSt-IUClZlOIl; The frame 1 is rabbeted as at 5 and against which is positioned the screen-body 4 and thelatter is connected to the frame 1 by aheading 6.

The endbar orrail 4 of the frame 1*is formed centrally with an opening 7 having a threaded wall and said bar 4 between the opening- 7 and one end thereof is provided with an opening 8 and between; the opening 4 and the other end there'ofwith an opening 9. 'lhe opcnings '7, 8 and 9aire disposed transversely with respect to the end bar 4.

As illustrated the extensionis shown coupled with the end bar4. The: extension consists of a flat plate 10 preferably constructed of thin metal and which is of a length corresponding to the width of the frame 1. The ends of the plate 10 are flush with the side bars of the frame 1. Secured to the'inne'r face of the plate 10 and flush with the outer side edge of the latter is a bar 11 which opposes the bar 4; and said bar 11 is of-the same length as the length of the plate 10. The platelOis positioned to slide against the front face of the b ary4 and said plate is slidably connected. to the latter. For the purpose of slidably con; necting the plate 10 to the bar 4 apair of coupling members 12, 13 are provided and each of which has its outer end anchored in the bar 11. Each coupling member is formed from a rod of cylindrical cross sec-1 tion and of substantial length and is provided with peripheral threads 14 at the outer. terminal thereof which engage in the bar 11 for fixedly securing 'the coupling member therewith, The inner end of each coupling member is formed with a head 15, The coupling: members 12 and, 13 slide through the openings 9, 10 respectively and the heads 15 are adapted to abut against the inner side edge of the bar 4. v

Carried by the bar 11 and .t-lrreadably engaging with thewall of the opening 8 is a rotatable adjusting element 15 for the extension. The element 15 extends -tl1l0llfi'll an opening 16 formed centrally of the bar 11, and the latter is provided with a socket 17 in which is seated the head 18 formed on the outer end of the element 15. The opening 16 communicates with the socket l7 and the latter is closed by a plate 19 Ill] which is secured by the holdfast devices 20 to the bar at. A mortise 21 is formed in the outer side edge of the bar 11 for the reception of the plate 10. The element 15 is formed from a threadedbolt of substantial length and which is rotatably connect ed with the bar '11 and projects a substantial distance from the inner edge of the bar 14. Secured to the inner end of the element 15 is a handle member 22 to facilitate the rotating of the element 15 for the purpose of adjusting the extension relative to the bar 4. The handle member 16 is formed with asocket into which extends the reduced inner end of the element 15 and said handle member and element 15 are secured together by a rivet or other suitable means as indicated at 23. The holdl'ast devices which are employed for securing the plate 10 to the bar 11 are imlicated at 24-. The width of the bar 11 is materially less than the width of the plate 10.

Carried by the coupling and adjusting elements 12, 13 and 15 are tension applying springs 25 for the extension element.

It is thought the many advantages of an extension for use in connection with window screens for the purpose referred to, in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of con struction can be had which fall within the scope of the invention as claimed.

What I claim is: b j

1. An extension'for window screens comprising a plate adapted to have its inner portion slidably positioned against one face of the screen frame, a bar secured to the outer portion of the inner face of said plate and adapted to oppose a side rail of the screenframe, a pair of: spaced, combined coupling and stopmembers fixedly secured at their outer ends in said bar and of a length to slidably extend through said rail and formed with heads at their inner ends to abut said rail, an adjusting element rotatahly mounted in and extending through and projecting from the inner side of said bar and having a head at its outer end abutting; in outer side of said bar and having a head at its outer end abutting in outer side of said har said element of a length to extend through said rail and having a portion thereof threaded for threaded engagement. with the rail and further provided with a handle at its inner end, and means secured to said bar for anchoring said element thereto.

2. An extension for window screens comprising a plate adapted to have its inner portion slidably positioned against one face of the screen frame, a bar secured to the outer portion of the inner face of said plate and adapted to oppose a side rail of the screen frame, a pair of spaced, combined coupling and stop members fixedly secured at their outer ends in said bar and ot a length to slidably extend through said rail and formed with heads at their inner ends to abut said rails, an adjusting element rotatably mounted in and extending through and projecting; from the inner side of said bar and having a head at its outer end abutting in the outer side of said bar, said element of a length to extend through said rail and having a portion thereof threaded for threaded engagen'ient with the rail and. further provided at its inner end with a handle, means secured to said bar for anchoring said element thereto, and coiled springs surrounding said members and elements and interposed between said bar and rail.

3. In combination a window screen frame having one of its end rails formed with a pair of outer openings and an intermediate openino, said openings extending trans rersely through said rail, the intermediate opening having the wall thereof threaded, an extension element slidably positioned against one face of the screen frame and having; a portion thereof opposing and spaced from said rail, combined coupling and stop members having their outer ends anchored into said portion, said members slidably extending through said outer openings and each having its inner end provided with a stop for abutting the inner side of said rail, a headed, rotatable adjusting element for said extension element, said extension element extending through said portion and having its head engaging in said portion to arrest said adjusting elements from bodily shitting inwardly through said portion, said adjusting element provided with peripheral threads engaging with the threads of the wall of said intermediate opening and adapted when m tatcd to adjust the extension clement relative to said bar, a. handle formed on the inner end of said adjusting element adjacent said rail, and means secured to said portion for anchoring, said adjusting element thereto.

In testimony whereof, I atlix my signature hereto.
